CURTAIN HA1 5 ING DEVICE Filed Oct. 22, 1930 Patented Jan. 19, 1932 PATENT OFFN'IE HERMAN KLEIN, OF CHICAGO, ILLINOIS CURTAIN RAISING DEVICE Application filed October 22, 1930. Serial- No. 490,386.

My invention relates in general to an improved device for raising a window curtain, and more particularly to a device for attachment to the upper ledge of the lower sash of the window, to raise the curtain as the sash is raised so that the lower edge of the curtain remains approximately even with the lower edge of the sash.

V The principal object of my present invention is to provide means for keeping the lower edge of the curtain substantially even with the lower edge of the window as the window is raised, to prevent soiling and damaging of the curtain as a result of the curtain blowing against the screen, or Window casing when the window is opened.

Another object is to provide a simple, I sturdy device for this purpose, which may be easy and inexpensive to manufacture.

Another object is to obtain these results without injuring the curtain in any manner, by wrinkling, kinking, or tearing in the place at which the curtain is held by my device.

Another object is to provide extension means in my device so that the curtain gripping means may be moved in a horizontal plane in position to correspond with the distance from the window at which the curtain is hung.

Other objects and advantages of the invention will be apparent from a consideration of the following detailed description taken with the accompanying drawings, wherein,

Fig. 1 is a front elevation of a window with the curtain in place in my device,

Fig. 2 is a sectional view taken on line 11 of Fig. 1 of the window with the lower sash raised, the curtain raising device of my invention being attached to the upper edgeof the lower sash of the window curtain in the position it assumes when held by my device as the window is raised,

' Fig. 3 is a perspective view of the preferred form of my device, as shown attached to the window in Fig. 2,

Fig. 4 is a side elevation of a modification of my device pivotally secured to the upper ledge of the lower sash, in such a way that it may be swung back over the window ledge when 59 not in use,

Fig. 5 is a front view with the curtain in section, of another modification, in which the upper arm is movable in a vertical plane,

Fig. 6 is a side elevation of the same showing the upper arm resting on the curtain which in turn is pressed against the lower arm or brush,

Fig. 7 is a fragmentary plan view of my device as constructed to fasten to the center of the upper ledge of the lower sash of the window so as to engage with the inner edge of (tihe curtains where a double curtain is use Fig. 8 is a side elevation of the same in position to engage the curtain for raising with the sash, and

Fig. 9 is a fragmentary side elevation showing position of the hinge and fragment of supporting arm when the latter is hanging down when not in use.

Referring now to the drawings, my device is fastened to the upper ledge of the lower sash of the window by means of screws through a bracket 2. Support 3 integral with the bracket and extending at right angles thereto, is a fiat metal piece with edges turned inwardly in the form of channels 6. In order that my curtain raising device may be adapted to any variation of the distance from the curtain to the window, I provide an extension 7 of the same construction as the outer metal piece 8, with metal rod 4 and shank 8 of brush 5 rigidly secured in the channels of extension 7, the whole slidably encased in the outer support 3.

In the use of my curtain raising device the window curtain 10 hangs from any ordinary curtain rod 9. WVith the window closed and the lower edge of the curtain hanging substantially even with the lower edge of the lower sash, each edge is held in a device 14 and 16. As the lower sash is raised to a position as shown in Fig. 2, the curtain 10 held on the bristles of the brush 5 is raised with the sash, the lower edge remaining in the same position relative to the lower edge 13 of the sash as when the window is closed. With the rod 4 to the rear of the brush as shown in Fig. 2 the curtain drapes as at 11, inside the curtain proper. The curtain so suspended presents a neat and even appearance, and there is no possibility that the lower edges will blow against the screen, against the window casing, or against the outside of the building, should the screen be removed. Not only will the curtain become soiled should this occur, but may also be torn and damaged.

The metal rod 4 may be either in front of the brush 5 as in Fig. 4, or to the rear, as in Fig. 2. The edge of the curtain is inserted in the same manner in each case, that is, under the rod and over the brush, but with the rod to the rear the curtain drapes in back of the lower portion, while with the rod in front the reverse is true.

It would be convenient at times to swing the curtain raising device back over the window ledge and out of the way. For this purpose I provide the metal support 3 made up in the manner above described integral with a U-shaped bracket 17 as shown in Fig. 4. Bracket 17 is pivotally secured to the U-shaped portion of bracket 19 by means of a pin 18 through holes in the upper and lower arms of brackets 17 and 19. Bracket 19 is secured in turn to the upper ledge of the window sash b means of screws 20 through the lower portlon of the bracket. This entire mounting is above the upper ledge of the lower sash of the window so that the device may be swung back over the ledge when not in use.

If one does not care to have the curtain looped under the metal rod 4 and over the brush 5 as shown in Fig. 2, I provide a modification, as shown in Figs. 5 and 6, whereby a metal rod 21 is rotatably secured in a groove 22 of support 23 of the same construction as the metal piece 3. The rod 21 moves in a vertical plane slightly inside the center of the brush and parallel thereto. The shank of the brush 5 is rigidly secured in the lower channel 24 of the support 23, the latter being at right angles to the brush and at an angle of about with the horizontal as shown in Fig. 5. The device can be secured to the window sash in either of the ways shown in Figs. 2 and 4. The window curtain 10 then hangs over the outer face of the brush. As rod 21 is dropped from a vertical to a horizontal position, the weight of the rod holds the curtain against the brush so that the bristles will grasp it slightly and hold the curtain in that position as the lower sash is raised. The curtain will then drape to the inside as the sash is raised with the lower edge of the curtain remaining in the same position as shown in Figs. 1 and 2.

If a double curtain is used, it is necessary to engage the inner edges of these curtains as well as the outer edges. For this purpose I provide my curtain raising device with laterally extending arms as shown in Fig. 7 The construction is substantially the same as that shown in Fig. 3, with supporting arm 3 channeled along its edges so that extension 7 b will slide therein. Brushes 5 and 5 together with rods 4 and 4 are rigidly secured to extension means 7", vertically displaced from one another as shown in Fig. 8. This embodiment of my invention is secured to the center portion of the upper ledge of the lower sash of the window by means of screws 26 through the bracket 27 of the hinge 28. The hinge 28 consists of the two Ushaped sections 29 and 31, the latter integral with supporting arms 3 of my device, and the former a part of bracket 27. They are hingedly connected by pin With my device in position as shown in Fig. 8 for engaging the edge of the curtain and raising or lowering the same as the sash is moved up or down, the flange 33 of the section 31 is supported by section 29 behind flange 34 of the same. With my device in this position pin 32 is rearwardly in the longitudinal slot 36, the latter in a horizontal direction. lVhen my device is not in use it may be dropped down parallel with the window. This is accomplished by raising arm 3 so that flange 33 clears flange 34, and then pulling the arm forward so that pin 32 is to the front of slot 36. Flange 33 will then drop down below flange 34 as shown in Fig. f), and my device will hang in a vertical pos1t1on.

The brush 5 which I have employed successfully in my curtain raising device is the type ordinarily used in cleaning the inside of small test tubes. The object is to have a brush with fairly stifl bristles which will pierce the curtain slightly but present a resilient surface for the curtain to drape over as it is raised in conjunction with the lower sash.

The embodiments of the invention described are only practical and convenient forms of the invention and it will be understood that other modifications could be made therein without departing from the spirit and scope of the invention.

What I claim is new and desire to protect by Letters Patent of the United States is 1.
